Grinding, drilling, and holing
Glass and mirror production services with accuracy in dimensions
Our production services also cover grinding, drilling and holing of glasses and mirrors. Edge grinding of glasses and mirrors are included in the basic work.
Something to note regarding the grinding methods
Some grinding methods have limitations in terms of the thickness and/or shape of the material. Our staff will gladly give more information on the matter.
Depending on the desired end product, our grinding services are categorized into the following list:
Sharp edge grinding
Sharp edges lightly ground, the straight part stays ungrounded. Cutting mark
Raw edge grinding
The edges, as well as the sides, are ground lightly flat. Opaque/coarse.
Gloss edge grinding
Edges are ground to 45°, the sides are ground straight and flat. Glossy.
C grinding
Edges are rounded. Opaque or glossy.
Miter grinding
Edges are ground into 45° and slanted (e.g. for an adhesive seam). Opaque or glossy. Only for thick glass, the small, straight part is left for the other edge.
Facet grinding
The edge is thinned to a thickness of around 3mm from the other side. The width of the facet depends on the thickness of the glass and what the customer desires. The facet part is polished, raw edge or opaque.
Holes
The glass is drilled with diamond-coated hollow tools from both sides of the glass to prevent edge cracking. In addition to this, the drill uses pressure to dispense a liquid coolant through the blades into the drillable target. The hole diameter can be 4-150 mm. For bigger orders, the drilling is done with machinery (CNC machinery). The holes can be ground matte if the radius is at least r8, and polished as long as the radius is at least r53.
Something to note regarding the tempering
If the drilled glass is tempered, it’s recommended to ask our staff in advance about the placement and size of the holes to ensure that the glass can withstand the toughening process.
